VALVE FOR GRANULAR MATERIALS.

Specification of Letters Patent.

Application led September 24, 1913.

Patented Nov. 10, 1914. Serial No. 791,454.

To all whom it may concern:

Be it known that I, VILLIAM H. ItoNEY, a citizen of the United States, residing at Gary, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Valves for Granular iMaterials, of which the following is a specichoke up due to the grain working between p the movable and the stationary parts. In this condition, the valve could be operated only with great difficulty, and furthermore it would not insure against leakage of the grain therethrough.

The primary object of my invention 1s to produce a valve which will never become choked, but on the contrary will always be freely operable, and whichnwill at all times positively prevent leakage of the gra-in therethrough.

Another object is to provide a valve of i this character which may be cheaply manufactured entirely from sheet metal.

Further objects and advantages relating to details of construction will be fully disclosed as the description proceeds.

In the accompanying drawings, Figure 1 is a vertical section on line 1 1 of Fig. 3 through one type of valve embodying the features of my invention. Fig. 2 is a horizontal section online 2 2 of Fig. 1. Fig. 3 is a plan view of the valve on a reduced scale. Fig. 4 is a section on line 4 4 of Fig. 3. Fig. 5 is a plan view of a modified form of valve embodying the invention. Fig. 6 is a side elevation of the valve shown in Fig. Fig. 7 is a vertical sectional view on line 7 7 of Fig. 8 showing another modification. Fig. 8 is a horizontal section on line 8 8 of Fig. 7

Referring to Figs. 1 to 4, the valve comprises asuitable casing consisting of an upper section 10 and a lower section 11, saidsections having their adjacent ends telescop-` ing one withinthe other.

12 indicates a conduit which fits within i the neck of the upper section 10 and delivers grain tliereinto, and 18 indicates another conduit fitting about the neck of the lower section to receive grain from the valve.` The lower section 11 has formed therein a ledge or shelf 14 upon which rests'. an annular valve seat 15. This valve seat is U-shape in cross section, as clearly indicated infF ig. 1, and the lower flange of the seathas a series of lsuitably formed legs 16 projecting downwardly and outwardly therefrom, said legs resting upon the ledge 14. If desired, each of these legs may be formed into an upwardly pointing ridge so that any grain coming in contact with the legs will freely slide therel from.- Below the ledge 14 the section 11 tapers downwardly to the neck within the conduit 13.

The upper flange ofthe valve seat 15 lies parallel to and closely beneath a horizontal ledge 17 formed in the upper casing section 10, and between the valve seat and said ledge 17 is a valve member 18 which may be a flat piece of sheet metal shaped to conform to the valve. The U-shape formation of the valve seat 15 and the provision of the legs 16 gives a resiliency to the valve seat which causes it to hold the valve member 18 tightly against the ledge 17. As indicated in Fig. 1, the interior of the valve seat 15 is preferably of greater diameter than the interior of the neck portion of the casing section 10, so that the grain flowing down through the section 10 when the valve is open will not be likely to lodge upon the valve seat 15.

An annular deflecting ring 19 has its upper portion fitting snugly within the upper end of the casing section 11, the lower portion of said ring being deflected inwardly in the manner of a hopper or a funnel.

At one side ofthe valve, the upper section 10 isyprovided with a horizontal eX- tension 20 having its opposite edges downwardly and inwardly turned to provide runways 21 for guiding the valve member 18 in its movements. v The extension 20 is cut away as at 22 to permit the operator to grasp the valve member 18.

Owing to the greater size of the valve grain will not clog the movement of the valve member nor will it prevent the tight closing of the valve. The deflecting ring 19 will cause the grain to pass inwardly so that it will not lodge upon the shelf 14, and the shape of the legs 16 and the spaces therebetween permit such grain to pass on into the downwardly converging portion of the lower casing section. Thus it will be seen that even if a quantity of'grain does collect to accommodate these valve members as they move outwardly to open the grain passage. Each of the valve members 23 has ixed thereto an arm 25, which arms are connected by links 26 to a longitudinally movable operating member 2"(v by which member the valve members 23 may be opened and closed. It will be understood that this valve is provided with a valve seat 28 similar to the valve seat 15 in Fig. 1, the seat 28 being held in place in any suitable way as by providing an annular depression or ledge in the. lower casing section upon which ledge the valve seat rests in a manner indicated in Fig. 1. The valve members 23 move between the upper flange of the valve seat and the ledge of the casing corresponding to ledge 17.y

In Figs. 7 and 8 is shown a valve having circular upper and lower casing sections 30, 31 and an annular valve seat 32. A disk 33 is suitably fixed at its edges to the upper casing section 30 and has a suitable number of openings 34 therein through which the grain may pass. The movable valve member 35 is in the form of a similar disk provided with corresponding openings 36, saidv valve member being mounted to rotate upon a pivot 37 fixed in the disk 33. The edges `of the valve member bear upon the valve seat 32. The valve member may be rotated to bring the openings 34 and 36 into and out of register by means of a pin 38 fixed in said valve member and extending upwardly through arcuate slots 39 formed in the disk 33 and the ledge of the upper casing section 30. In this type of valve the deiecting ring corresponding to 19 in Fig. 1 is not necessary inasmuch as grain is not likely to find its way into the space at the outside of the valve seat 32.

It will be seen that I have produced a valve construction which is non-chokable,

simple in construction, and cheap to manufacture. While I have herein shown the preferred forms of my invention, I would have it understood that I do not thereby intend to limit the invention to the constructions disclosed inasmuch as the type or form of the valve may be varied in many ways without departing from the essential characteristics of the invention in its broader aspects.

I claim as my invention:
